Bioswale Work Session and AWS EARTH DAY Cleanup

Saturday, April 20, 2024

AWS sent us 54 volunteers for the Earth Day Cleanup, with 6 leaders for Earth Day, plus we had 20 volunteers for the bioswale, for a grand total of 76 volunteers.  ACBA clubs represented today were CRC, NCAWPA, and DCSRC.   What a terrific crowd!  Four groups cleaned up in our usual places - our own shoreline, M St SE, Barney Circle, and the hiker biker path up to and beyond the Congressional gate.  A total of 36 bags of trash and 18 bags of recyclables were collected. 

A special thanks for Tamara, Will Cyphers (DCSRC) and Jim Smailes for sending the great photos!

Kick off 2024  Bioswale Work Session 

Sunday, March 24, 2024

A small volunteer team of 5 addressed two invasive species today.  The first is Lesser Celandine, now appearing in all sections.  The second is bush honeysuckle, section 1 for today, but there's more in section 4 (next month).  


Tasks accomplished today

 Removed Lesser Celandine in Section 2

 Pulled & dug up bush honeysuckle, section 1

 Pulled vines from the River Birch, section 1 

Removal of wineberry & sweet autumn clematis, section 2 






Amy begins to dig out Lesser Celandine.  Masses of it showed up this spring

along the edge of the seawall, apparently deposited there by the river.   



Dominique and Amy dig deep to remove Lesser Cellandine.  They put the highly invasive plants in plastic bags, along with the dirt so as to not drop bits of roots or bulbils, which quickly can grow into many new plants.  First time we've had to do this, and it turned out to be heavy work.  

Gabriella tackles significant growth of Lesser Celandine by the ramp, sec 1 

 IF WE DON"T DO ANYTHING.... Lesser Celandine grows to the exclusion of native species

Gabriella pulls bush honeysuckle (green bushes) in section 1 

What's next?  Jim and Gabriella view a thicket of bush honeysuckle (green under the tree) and decide how to proceed. 

IF WE DON"T DO ANYTHING.... bush honeysuckle grows tall and thick, to the exclusion of native bushes and trees (as in this view of the side of the road, M St near the boathouse.
